Simulation tests of fleet vehicles periodic inspections timeliness: a case study

This study analyzed the case of a medium-sized workshop and the income from servicing individual customers. The management of the company observed some unused potential in the garage and plans to sign contracts with fleet customers for comprehensive maintenance of their vehicles. The key question was how many fleet vehicles could be additionally serviced without losing individual customers? In this work, a simulation model of a workshop was developed, treated as a system for queuing orders and vehicles. The model includes a subsystem of random generation of fleet vehicle mileage during the simulation. The idea of event-driven simulation and the Matlab/Simulink SimEvent environment library was used.

Analysis of Performance Bottlenecks in Multithreaded Multiprocessor Systems

The performance of modern multiprocessor systems is often limited by the delays of interconnections or long latencies of memory subsystems. Instruction-level multithreading is a technique to tolerate such long latencies by switching from one instruction thread to another and continuing instruction execution concurrently with the long-latency operations. Using timed Petri net models, the paper analyzes performance limitations introduced by different components of distributed-memory multithreaded multiprocessor systems. Simulation results are used to compare performance improvements obtained by replicating critical components of the system to those obtained using components with better performance characteristics.
